Because they generate Crypto and Crypto is what we send to Ukraine to help the Refugees and their Pets !

Cryptocurrency donations accomplish several objectives: they avoid heavier fees charged by traditional financial networks, transfers are nearly instantaneous, and the digital tokens are mobile — they can be given by anyone and accessed by the owner regardless of their location.
“There are close to two million Ukrainians that have fled into Europe and other countries and they had to do so quite rapidly,” Gladstein said. "Think about a middle-class family. You probably have some stocks and own a house or part of a house. You can’t bring any of that with you. Ukraine is the fourth most crypto-friendly country in the world in terms of per-capita ownership, so those who fled probably were able to take advantage of an asset that could just go with them.

Crypto donations are also making a difference for Ukrainians, both in and out of the country. Ukraine’s banking system is hardly operating, but the major crypto exchanges are available 24/7 from a phone or computer.
Crypto-based collaborations like Unchain Fund and UkraineDAO (an abbreviation for decentralized autonomous organization) took shape in the first few days of the crisis. Unchain has raised more than $6.9 million in 10 cryptocurrencies since Feb. 25 for relocation support, transportation, food and medicine. Three million Ukrainians in other countries need money for housing, living costs, and psychological and professional support. Crypto has proved useful for displaced people, who need access to stable funds and the ability to convert crypto into fiat currency in a flexible way. We’re also distributing the Unchain Help Card, a crypto-to-consumer debit card, to help mothers with young children purchase supplies.
